Fifteen patients were tested before and after treatment in a multifaceted inpatient program for chronic low back pain to determine if a gradually progressive activity program affected gait performance and physiological capacity. Before treatment, all patients demonstrated decreased physiological conditioning by higher-than-expected values for oxygen consumption and heart rate and by lower-than-normal gait velocity, stride length, and cadence. After treatment, an increase in mean walking velocity of 19 meters/minute reflected parallel gains in cadence and stride length. Improved mechanical performance resulted in improved "energetics." Energy spent per unit of distance walked decreased by 18 percent after treatment, providing a useful measure of increased physiological efficiency. Results indicated that patients with chronic low back disability can derive significant conditioning effects from an exercise program based on general function.
15名慢性下腰痛患者在一个多方面的住院治疗项目前后接受了测试，以确定一个逐渐递增的活动项目是否会影响步态表现和生理能力。治疗前，所有患者均表现出生理机能下降，其耗氧量和心率高于预期值，且步态速度、步幅和步频低于正常水平。治疗后，平均步行速度提高了19米/分钟，反映出步频和步幅相应增加。机械性能的改善带来了“能量学”方面的改善。治疗后，每步行单位距离所消耗的能量减少了18%，这为生理效率提高提供了一个有效的衡量指标。结果表明，患有慢性下腰痛残疾的患者可以从基于一般功能的运动项目中获得显著的机能改善效果。
